紫外线的

Armed with this information and further analyses, Rumble, lead author Bekker, and colleagues propose the following scenario today in Science . Early in Earth's history, volcanic eruptions spewed massive amounts of sulfur dioxide into the atmosphere, where UV sunlight broke down the gas and created the odd sulfur isotope ratios. The sulfur descended with the rain and accumulated into sedimentary beds on the sea floor. Once there, superheated water from geothermal vents at various locations on the sea floor cooked the sulfur into sulfide. Finally, nickel-bearing magma welled up from Earth's mantle, combining with the sulfide to form nickel sulfide and encasing the compound inside volcanic rock called komatiite.

凭借这份资料和进一步的分析，朗布尔、研究论文的第一作者贝克及同事们今天在《科学》杂志上提出了如下的推测：在地球早期的历史上，火山爆发将大量的二氧化硫气体喷射到空中，太阳的紫外线将其分解，产生了奇特的硫同位素比值，这种硫随雨降下，积存于海底沉积层中；一旦到达海底，海底各处的地热出口所产生的温度过高的水把硫加热成硫化物；最终含有镍的岩浆从地幔中涌出，跟硫化物结合形成硫化镍，并将硫化镍包裹在一种叫做"科马提岩"的火山岩中。

Contain special ZTP and 6 kinds activity grass family cream compound, the sufficient nutriment breathes out on the fur organization who protects a pet , effective improvement in daily nursing , hoarse and diverge since the hair that the hard comb , unitary dog grain and ultraviolet ray lead to is dark specifically for being short of the nutrient quilt hair,daily usage can reach it does not matter whether to bestow favor on hair briskly or not.

Boehmeriae were studied, and the results indicated that the zoospores of P. boehmeriae could be inactivated obviously by irradiating with 30W ultraviolet light 50cm away from the culture dishes tested and that 95% germination of zoospores could be restrained by 30W ultraviolet light treatment for 40sec.The mycelium growth from mycelium discs of P. boehmeriae were inhibited mostly by 30W ultraviolet light treatment for 20min. Afterwards, the inhibitive rates were decreased with the rise of the treatment time, which showed that the mycelium discs of P. boehmeriae had produced flexibility to ultraviolet rays after being irradiated by certain dosage of ultraviolet light.

研究了紫外光对苎麻疫霉生物学特性的影响，结果表明，30W的紫外灯管距培养皿50cm照射处理对苎麻疫霉的游动孢子具有明显杀灭作用，紫外光照射40sec可以抑制95%的游动孢子萌发；紫外光照射20min对菌丝块的菌丝生长的抑制率达最大，以后随着处理时间增加，抑制率却有降低的趋势，说明苎麻疫霉的菌丝块，经一定剂量紫外光照射后对紫外线产生了适应性。

Noggin induces the nerve tube formation. It binds and inactivates members of the transforming growth factor-beta superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). Proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) are related to noggin mutations.

For maintain the genome integrity and fidelity. DNA repair processes are classified into pathways responsible for repairing specific classes of DNA damage, although recent data indicated that some proteins function in multiple pathways. Base excision repair occurs through excision of a damaged region, followed by fill-in repair synthesis using the opposite strand as a template. Mismatch repair operates on base mismatched and small loop-outs that arising during replication by misincorporation or slippage on the template strand. Nucleotide excision repair removes photoproducts from u.v. radiaton and bulky adducts from a multiple of chemicals. DNA double-strand breaks may be rectified by either homologous recombination repair and nonhomologous end joining pathways where both strands of the DNA duplex are damaged.

DNA修补基因可藉由不同的机制对不同程度的DNA损害进行修复，虽然近来已有文献指出，一些DNA修复蛋白可能参与多种DNA修复机制，不过一般可分为下列四种DNA修复机制：碱基删除修复(Base Excision Repair； BER)，即对较小的DNA损伤，进行修复；核苷酸错误配对删除修复，即对复制时所产生的核苷酸配对错误或模板滑动造成的DNA损害进行修复；核苷酸删除修复(Nucleotide Excision Repair； NER)，即对因紫外线或有机化合物所造成的较大损伤进行修复；以及双股DNA断裂修复(Double-Strand Breaks； DSBs)，即对双股DNA断裂进行修复，此机制又可分为同源染色体的重组与末端接合两种主要路径，对受损的DNA进行修复。
